Application filed september 18, 1920. Serial No. 411,026.

to provide a device of this character which may be used for stropping st-raight razors.

A further object ofthe invention is .to provide a device of thiswcharact'er which may be cheaply constructed, and which, is particularly; adapted for use in barber shops, and the like. g

Other objects and advantages of-the in vention will become apparent,throughout the course of the followingdeScription,

In the accompanying drawings, wherein I for the purpose of illustration is shown a preferred embodiment of my invention, and wherein like reference characters designate like parts throughout;

Figure '1 is a plan View of a razor stropping machine constructed in accordance with my invention;

Figure 2 is a side elevation partly in section thereof;

Figure 3 is a section on the line 33' of Figure 2; V

Figure i is a detail View showing the pul ley shifting mechanism, and

Figure is an end elevation of one of the pulley bearing shafts and pulley.

Referring now more particularly to the drawings, the numeral 10 indicates a suitable base, having mounted centrally thereof a motor 11 the armature shaft 12 of which is disposed transversely of the'base and is provided upon its end with pulleys 13 and 1a.

Mounted in bearings 15 are shafts 16 and 17 disposed upon opposite sides of the motor and bearing rollers 18 and 19 respectively. The outer ends 20 ofthe shafts 16 and 17 beyond bearings 15 are provided with lugs 21 adapted to coact with notches 21 formed in pulleys21 which pulleys are normally rotatable upon the Shafts beyond such lugs.

.Means for shifting/the pulleys 21 to bring them into engagementwiththe lugs of their respective shafts areprovided conone end of the base andhaving bifurcated upper ends 24: engaging in. the groove an a en .sisting in levers. 22 pivotally connected at formed by an extension 25 upon the pulleys.

An operating.thumb piece 26 is connected .to the..lever,s -22 for shifting the same. a.

Pulleys 21 are connected with the pulleys 13 and 14 and with the armature shaft 12 by means of belts 27 and 28.

At opposite ends of the base 10 and extending transversely thereof are shafts 29 1 and 29 bearing rollers 30 and 31, respectively, the endsof the shafts being mounted in suitable antifriction bearings 32. These bearings are supported upon' transversely extending plates 33. 1

EXtending inwardly from eachend of the base at the approximate center thereof are-slots having formedin the side walls .thereof grooves 36. Formed onftheunder surface of eachof-the plates 33 is a downwardlyextending portion extending into .the slot v35and embodying shoulders 38 engaging in the grooves 36. It will be obvious that the plates 33 are longitudinally shiftable upon'the base, but are held against angular displacement with relation thereto. I Extending longitudinally of the slot is a threaded shaft 39 held against longitudinal shifting and provided upon its outer end with a knurled thumb nut by means of which-itmay be rotated. These shafts extend through threaded openings 40 formed in the downward extensions 37 of the plates 33 and have threaded engagement therewith, whereby rotation of the thumb nut will cause shifting of its associated plate longitudinally of the base. Extending about the rollers 18 and 30 is a canvas sharpening belt 42 and extending about the rollers 19 and 31 is a leather finishing belt 41.

It will be seen that by adjustment of the thumb nuts the belts 41 and 42 may be tightened as desired, and itwill likewise be seen that either of the belts may be driven from the motor singly or both belts may be driven simultaneously as desired. I prefer that the motor 11 shall be of the reversible type in order to permit driving of the belts in either direction.

Extending upwardly from the sideand.

ends of the base are side and ends Walls 43 combining with the base to form a casing which is normally closed by a' cover 4% in order to protect the belts and their associated mechanism from dust and dirt when not in use. r 7

It will be obvious that my device, by rea son of its simplicity, is particularly Well adapted forthe use for which it is intended, and it will likewise be obvious that the construction of the same as hereinbefore set forth may be altered somewhat Without in any manner departing from the spirit of my invention. 1 accordingly do not limit myself toothe specific structure as herein bet-ore set forth, except as so limited by the subjoined claims. r

VVha tI claim is; r .1. In a razor stropping device, a casing including abase, a reversible motor arranged on the base vvitnin the casing and having the armature shaft thereof eXtending transversely ot the base, a pair or" shatts Y rotatably mounted upon said base to one side of said motor, means operable from the exterior of the casing for adjustably varythe distance between the shafts of said pair, a stropping belt driven by the pair of shafts, and means for connecting'saidpair of shafts to the armature shaft of said motor to be driven thereby, comprising a pulley secured tosaid armature shaft, a second pulley mounted upon one shatt of said 'pairot shafts, means operable from the e;-

terior of the casing for shifting said second pulley longitudinally of said shatt, and a lug formed upon the shaft bearing the sec ondpulley, said second pulley being probase and having thearmature shaft thereoi' extending transversely of the base, a pair of parallel shafts rotatably mounted upon said base, means for adjustably varying the distance between the shafts of said pair, comprising a member extending transversely ,of the base at'the end thereof upon which one of the shafts of the pair is rot-atably mounted, said transversely extending memher being provided with a downwardly entending portion provided upon'the sides thereof with outstanding shoulders, said base having formed in the end thereof a longitudinally extending slot having grooves formed in the side Walls thereof, said down- Wardly extending member being slidably mounted on said slit and having the shoulders thereoi engage in the grooves, a shaft rotatably mounted approximately centrally of saidslot and held against longitudinal HlOVQi'ilGDl) therein, said shaft having threaded engagement With said downwardly extending member, and having an end portion thereof extended exteriorly of the oas-' ing and provided with means-whereby it I may be rotated, a stropping belt driven by I the pair "of shafts and means operable from v the exterior of the casing for connecting one of said pair of shafts to the armature shaft of the motor to be driven' thereby.

In testimony whereof I hereunto affix my signature.
